Raichel, I was like you in high school. I didn't have many friends but I'm lucky that I went to a good school that stressed academics. I enrolled in many advanced placement classes so I didn't get bullied much. I also had a few friends who understood me. During lunchtime, I sit with my friend(s), but when my friend was absent and I had no one to sit with, I would go hide in the bathroom and just eat there. I was afraid of sitting out there in the loud cafeteria all alone.
When I'm in class, I usually talk to guys who are just like me; nerdy and a bit awkward. I feel like I connect better with them. But I don't mind being alone in class; when people are busy socializing with each other, I try to do my homework and study instead.
I have already graduated from high school, but I did consider dropping out of college. College was when h-ll and brimstone started for me. I lived in the dorm for 2 years and people noticed something awkward about me. I didn't have great social skills, so that made things worse. I was isolated, taunted, and bullied. The college that I went to was a big party school, and it was a mistake going there. I finally dropped out of it and switched colleges several times. I didn't feel like I fit in anywhere. I did have suicidal thoughts. But eventually, I'm glad I found a small college near home that I liked.
Anyways, sorry for the long story. Here's my conclusion: Don't drop out of high school. Many jobs today require at least a high school education, and if you don't have that, you'll be at a big disadvantage. Try to finish high school, and if possible, find someone who can teach you communication and social skills. After you complete high school, many doors will open for you. If you want to work alone, maybe consider a career as a truck driver, accountant, pilot, etc.
